A DeKalb County apartment complex went up in flames early Tuesday morning, sending families out into the streets. It happened around 4:30 a.m. at Eagles Run Apartments at 2000 Bouldercrest Road. Officials say the fire appears to have started in a first-floor unit. The fire is now out. One person was treated at the scene for smoke inhalation but no one had to be taken to the hospital for treatment. Fire officials tell us three units were damaged displacing three families. They say three other units may have smoke damage. The Red Cross has been notified to assist those affected. A resident at the complex tells us this is not the first fire he has seen at these apartments. He said this is the fourth fire that he’s seen in the four years that he has lived there. The cause of the fire is unknown and is under investigation.
